Habitat and Biodiversity Loss: The Sixth Extinction
				As the human population and land development increases, more and more habitats are impacted. Today, we may be losing 30,000 species a year -- a rate much “faster than at any time since the last great extinction 65 million years ago that wiped out most of the dinosaurs. Estimated rate is 1,000 - 10,000 times above normal “background level.”
